validation.py - KeyError

[inui-sdt2]

Dear Matthias-san and all

I get the following error in rare cases when using validation.py.
What kind of case is the possible causes?
It works if I retry, so I've implemented retry logic now.

/pyhanko/sign/validation.py", line 2540, in _cms_objects_to_streams

Hi Inui-san,

Thanks for checking in.

That KeyError is actually handled within the normal scope of operations of _cms_objects_to_streams, so I'm assuming that the real error is triggered somewhere in this piece of code. It might have ended up in a part of the stack trace that was cut off from your post. Could you look into that?

thank you for this advice.I think It's CA side issue. but I will look into details.
